• Recursive utility and the equity premium puzzle: A discrete-time approach 

      Aase, Knut K. (Discussion papers;2013/03, Working paper, 2013-05)
      We study the Epstein-Zin model with recursive utility. Recognizing that recursive preferences implies that the underlying model is not Markovian, we use methods not depending upon the Markov property to solve the model. ...
    • Recursive utility using the stochastic maximum principle 

      Aase, Knut K. (Journal article; Peer reviewed, 2016)
      Motivated by the problems of the conventional model in rationalizing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in a continuous-time model. We use the stochastic maximum ...
    • Recursive utility using the stochastic maximum principle 

      Aase, Knut K. (Discussion paper;03/14, Working paper, 2014-02)
      Motivated by the problems of the conventional model in rationalizing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in a continuous time model. We consider ...
    • Representation of preferences á la Savage with a general probability measure 

      Aase, Knut K. (Discussion paper, Working paper, 2001-10)
      This paper addresses two weaknesses of the subjective expected utility representation of Savage: The first is that the resulting subjective probability measure P is atomless only, the second is that P is only finitely ...
    • The St. Petersburg Paradox 

      Aase, Knut K. (Discussion paper, Working paper, 1998-09)
      The classical St. Petersburg Paradox is discussed in terms of doubling strategies. It is claimed that what was originally thought of as a "paradox" can hardly be considered as very surprising today, but viewed in terms of ...
    • Strategic insider trading equilibrium : a filter theory approach 

      Aase, Knut K.; Bjuland, Terje; Øksendal, Bernt (Discussion paper, Working paper, 2010-08)
      The continuous-time version of Kyle's (1985) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing time-varying liquidity trading, and by having weaker ...
    • Strategic insider trading equilibrium : a forward integration approach 

      Aase, Knut K.; Bjuland, Terje; Øksendal, Bernt (Discussion paper, Working paper, 2007-11)
      The continuous-time version of Kyle’s (1985) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing time-varying noise trading, and by allowing the orders ...
    • Strategic Insider Trading Equilibrium with a non-fiduciary market maker 

      Aase, Knut K.; Øksendal, Bernt (Discussion paper;2/19, Working paper, 2019-08-28)
      The continuous-time version of Kyle's (1985) model is studied, in which market makers are not fiduciaries. They have some market power which they utilize to set the price to their advantage, resulting in positive expected ...
    • Strategic insider trading equilibrium: A filter theory approach 

      Aase, Knut K.; Bjuland, Terje; Øksendal, Bernt (Journal article; Peer reviewed, 2012)
      The continuous-time version of Kyle’s (Econometrica 53(6):1315–1336, 1985 ) model of asset pricing with asymmetric information is studied, and generalized in various directions, i.e., by allowing time-varying liquidity ...
    • Strategic Insider Trading in Continuous Time: A New Approach 

      Aase, Knut K.; Øksendal, Bernt (Discussion paper;3/19, Working paper, 2019-08-29)
      The continuous-time version of Kyle's (1985) model of asset pricing with asymmetric information is studied, and generalized by allowing time-varying noise trading. From rather simple assumptions we are able to derive the ...
    • The equity premium in a production economy; A new perspective involving recursive utility 

      Aase, Knut K. (Discussion paper;15/15, Working paper, 2015-04-10)
      We study a rational expectations' competitive equilibrium in a production economy, i.e., a system of prices at which firms' profit maximizing production decisions and individuals' preferred affordable consumption choices ...
    • The Life Cycle Model with Recursive Utility: New insights on optimal consumption 

      Aase, Knut K. (Discussion papers;19/14, Working paper, 2014-05)
      We analyze optimal consumption, including pensions, during the life time of a consumer using the life cycle model, when the consumer has recursive utility. The model framework is that of continuous-time with diffusion ...
    • The optimal extraction rate versus the expected real return of a sovereign wealth fund: Some simulations 

      Aase, Knut K.; Bjerksund, Petter (Discussion paper;7/19, Working paper, 2019-09-06)
      With reference to funds established for the benefits of the public at large, a university endowment, or other similar sovereign wealth fund, we demonstrate that the optimal extraction rate from the fund is significantly ...
    • The Perpetual American Put Option for Jump-Diffusions 

      Aase, Knut K. (Journal article; Peer reviewed, 2010)
      We solve a specific optimal stopping problem with an infinite time horizon, when the state variable follows a jump-diffusion. The novelty of the paper is related to the inclusion of a jump component in this stochastic ...
    • Using option pricing theory to infer about equity premiums 

      Aase, Knut K. (Discussion paper, Working paper, 2005-11)
      In this paper we make use of option pricing theory to infer about historical equity premiums. This we do by comparing the prices of an American perpetual put option computed using two different models: The first is the ...
    • Wealth Effects on Demand for Insurance 

      Aase, Knut K. (Discussion paper, Working paper, 2007-01)
      A standard result states that under decreasing absolute risk aversion the indifference premium of the insured is a decreasing function of wealth. This has been interpreted to mean that insurance is an inferior good, which ...

      Aase, Knut K. (Discussion paper;2012:13, Working paper, 2012-11)
      Motivated by the problems of the conventional model in rationalizing izing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in continuous time. In a representative- agent ...
